How to use?

Take Claritin only according to your prescribed dosage, without increasing or decreasing your dose. It is advisable to take Claritin until your symptoms have cleared up, or until prescribed by your doctor. Claritin should not be given to children under two years of age as misusing cough and cold medicines can lead to death in young children. It is advisable to take Claritin once every day unless prescribed otherwise by your doctor. You can take Claritin with food if you feel nauseous. Make sure you swallow the whole regular tablet, without chewing, breaking, or crushing the tablet as this can affect your dosage. If you are taking the liquid form, use a dose-measuring device to make sure you take the correct dosage. If you are taking the chewable tablet, you need to chew it before swallowing. Store Claritin in a cool and dry place.
